Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle assembly technology, specifically relating to an auxiliary assembly device for energy storage battery packs in a semi-enclosed compartment. Background Technology

[0002] Solar-powered drones are a type of unmanned aerial vehicle that uses sunlight as its sole energy source and employs an all-electric architecture. The drone's overall design prioritizes lightweight construction, utilizing composite materials such as carbon fiber and epoxy resin. The energy storage battery compartment is the structure on the solar-powered drone used to install the energy storage battery pack. To reduce weight, the overall design adopts a truss structure, presenting a semi-enclosed form externally, with internal interfaces for connecting to the energy storage battery pack. This semi-enclosed structure presents challenges in the energy storage battery pack assembly process, including cumbersome procedures, limited operating space, and low efficiency.

[0003] Before and after the drone flight test, the installation and disassembly of the energy storage battery pack and the cabin section need to be completed respectively. The main considerations are the transportation volume and the energy characteristics of the energy storage battery pack, which require separate transportation.

[0004] Multiple energy storage battery packs are housed within the energy storage battery compartment, arranged in a series along the compartment's axis. Sometimes, due to the need to coordinate the drone's front and rear center of gravity, the installation area of ​​the battery packs within the compartment may need to be adjusted, requiring on-site operators to adapt accordingly. Due to the compartment's truss structure, confined internal space, and the large weight and energy content of the battery packs, the assembly process is cumbersome, inefficient, and carries certain safety risks.

[0005] The current assembly method has some shortcomings, as detailed below:

[0006] (1) It requires 4 or more people to complete the operation, of which 2 people are responsible for the continuous fixing and limiting of the compartment, and the other 2 or more people realize the manual movement and mechanical interface connection within the energy storage battery compartment.

[0007] (2) Due to the large weight of the energy storage battery pack and the material of the contact surface with the compartment, the friction of the contact interface is large, making the pushing process difficult and prone to excessive force, which can lead to structural damage and poses a risk of damage.

[0008] (3) The current method for operators is to manually lift the energy storage battery pack from below the compartment to overcome its gravity and move it along the axis until it reaches the designated area. The work space is concentrated below the compartment. This method is dangerous and easy to tire the operators, and the process is complicated.

[0009] (4) The reliability is not high. The energy storage battery pack contains energy, and accidental drops may cause safety problems.

[0010] A search of relevant literature and patent information yielded no similar literature or patent reports.

[0011] The auxiliary assembly device for energy storage battery packs involved in this invention, compared with existing assembly methods, not only has a compact structure and meets the requirements for strength and rigidity, but also has significant advantages such as reduced number of operators, improved efficiency, and stable and rapid process. Furthermore, this auxiliary assembly device can be adjusted within the design range, changing the motion interface between the energy storage battery pack and the battery pack compartment from direct contact to a motion interface between the energy storage battery pack and the universal ball bearing surface of the auxiliary assembly device. This allows the energy storage battery pack to slide with very little external force, avoiding mechanical damage to the battery pack and compartment structure caused by collisions due to excessive force, and also improving reliability and safety. Summary of the Invention

The bottom of the height lifting module is mounted on the base module, and the top is fitted with a sliding module. The energy storage battery pack is placed on the sliding module, and the sliding module, through a ball-bearing surface contact motion interface, enables the energy storage battery pack to move with two degrees of freedom and rotate with one degree of freedom within a certain height plane, completing the entry and exit of the energy storage battery pack into the compartment. The height lifting module, in conjunction with other mechanisms, adjusts the height to avoid interference with the compartment's structure, completing the auxiliary assembly of the energy storage battery pack within the compartment.

[0015] Preferably, the sliding module includes a universal ball, a cylindrical pad, and a platform;

[0016] The omnidirectional balls are connected to the cylindrical pads via fasteners, and the cylindrical pads are then connected to the platform via fasteners. The omnidirectional balls are arranged in an orderly manner on the platform plane, reasonably avoiding the space for cable laying and the interference space of the cabin rods. The platform is used to connect with the height lifting module.

[0017] Preferably, the ordered distribution is that the omnidirectional balls are evenly distributed on both sides of the platform; in the middle area, in order to ensure load-bearing and sliding stability, an equilateral triangle configuration is adopted, that is, every 6 omnidirectional balls form an equilateral triangle, and the triangles are distributed in opposite directions in the central direction.

[0018] Preferably, the height lifting module includes a lead screw, a worm gear reducer, a rocker wheel, and a guide column;

[0019] The worm gear reducer is connected to the sliding module and works with the lead screw. It raises and lowers the height through the rocker wheel, which drives the sliding module to complete the height adjustment. The guide column is installed on the sliding module to guide the lifting process.

[0021] Preferably, the swing bracket [8] includes a swing bracket mounting structure, a swing bracket rotating structure, and a swing bracket contact structure; the lower end of the swing bracket mounting structure is connected to the base module through fasteners, and the upper end is mounted on the swing bracket contact structure through the swing bracket rotating structure; the swing bracket rotating structure drives the swing bracket contact structure to achieve the rotation function and complete the avoidance during the bearing process; the upper end of the swing bracket contact structure is provided with a U-shaped groove for contacting the base module to achieve the limit.

[0022] Preferably, a polymer material is disposed on the U-shaped groove to increase friction and provide cushioning; the polymer material is nitrile rubber.

[0023] Preferably, the base module includes a base structure, rollers, and feet; the base structure is a truss structure, the rollers are connected to the bottom of the base structure to enable the overall movement of the device, and the feet are connected to the bottom of the base structure to enhance stability during assembly.

[0024] A method for assembling an energy storage battery pack using the aforementioned auxiliary assembly device includes:

[0025] The auxiliary assembly device for the energy storage battery pack was moved to the designated area and its balance and stability were adjusted.

[0026] Rotate the swing bracket to position it so that it avoids interference with the energy storage battery pack compartment structure;

[0027] After transporting the compartment to the top of the auxiliary assembly device and determining the load-bearing area, rotate the swing bracket to the load-bearing state, lower the compartment until it is in complete contact, and connect the limiting hole and the limiting pin of the connecting device. At this time, the relative positional relationship between the compartment and the device is determined.

[0028] The height adjustment module operates, and the height of the sliding module platform is adjusted to be relatively consistent.

[0029] The energy storage battery pack to be assembled is placed on top of the omnidirectional ball of the sliding module. Due to gravity, the energy storage battery pack naturally comes into contact with the array formed by the omnidirectional ball.

[0030] The energy storage battery pack achieves stable sliding into the compartment under the action of external force. The external force is applied to the operable areas on the side and below the compartment. When the energy storage battery pack reaches the mechanical interface area connected to the compartment, the height is lowered by the height lifting module and it contacts the mechanical interface of the compartment. During the descent process, the energy storage battery pack achieves 2 degrees of freedom of movement and 1 degree of freedom of rotation adjustment in the plane through external force, realizing the adaptation and adjustment of the mechanical interface.

[0031] Secure the energy storage battery pack to the compartment, and the installation process is complete.

[0032] A method for disassembling an energy storage battery pack using the aforementioned auxiliary assembly device includes:

[0033] The auxiliary assembly device for the energy storage battery pack was moved to the designated area and its balance and stability were adjusted.

[0034] Rotate the swing bracket to position it so that it avoids interference with the energy storage battery pack compartment structure;

[0035] The module with the installed energy storage battery pack is moved above the auxiliary assembly device. After the load-bearing area is determined, the swing bracket is rotated to the load-bearing state, and the module is lowered to complete contact. The limiting hole and the limiting pin of the connecting device are then connected. At this time, the relative positional relationship between the module and the device is determined.

[0036] The height adjustment module is operated to adjust the height of the sliding module platform to be relatively consistent, so that the array formed by the omnidirectional ball contacts the bottom of the energy storage battery pack;

[0037] The connecting parts between the compartment and the energy storage battery pack are disassembled. External force is used to make the energy storage battery pack slide stably out of the compartment, thus completing the disassembly.

[0038] The advantages of this invention compared to the prior art are:

[0039] (1) In the auxiliary assembly device for energy storage battery packs in this invention, the operator places the compartment on the device and fixes it, which realizes the relatively reliable fixation of the two, solves the problem that the operator needs to be dedicated to limiting the compartment during the assembly process, and reduces the number of operators required.

[0040] (2) The energy storage battery pack auxiliary assembly device of the present invention changes the motion interface between the energy storage battery pack and the battery pack compartment from direct contact to a motion interface between the energy storage battery pack and the universal ball bearing surface of the auxiliary assembly device. By changing the contact surface type, the operator can use a small external force to gently push the energy storage battery pack placed on the device to achieve rapid and stable movement within the compartment in a relative sliding manner, and has the adjustment capability of 2 degrees of freedom of movement and 1 degree of freedom of rotation in the height plane; it solves the problem that the operator has difficulty assembling the energy storage battery pack due to the narrow space of the semi-enclosed compartment and the large friction of the contact surface, reduces the operator's skill requirements, and alleviates the operational pressure during the assembly process;

[0041] (3) The auxiliary assembly device for energy storage battery pack in this invention avoids the need for operators to move the energy storage battery pack under the compartment for a long time to overcome gravity and lift the battery pack to complete the movement and adjustment. The operation can be achieved through the truss space on the side of the compartment.

[0042] (4) The energy storage battery pack auxiliary assembly device in this invention reduces the complexity of the assembly process, improves the reliability and stability of the energy storage battery pack and compartment assembly process, reduces the occurrence of collisions, drops and other problems, and releases the risk of accidental assembly of energy-containing components.

[0063] The following is in conjunction with the appendix Figure 1-20 The present invention will be described in detail below.

[0064] An auxiliary assembly device for energy storage battery packs is disclosed, which mainly consists of sliding modules, height lifting modules, load-bearing limiting modules, and a base. In use, the operator first places the energy storage battery pack compartment on the base of the auxiliary assembly device, connecting the two via the mechanical interface, i.e., the load-bearing limiting module, until they are relatively stationary. Next, the operator adjusts the travel of each height lifting module in the height direction, ensuring the relative height between the sliding modules is within a certain allowable error range. Finally, the operator uses a small amount of external force to gently push the energy storage battery pack placed on the device, achieving rapid and stable movement within the compartment through relative sliding. Once the designated assembly area is reached, the device height is lowered to contact the compartment, and the bolts are tightened, completing the connection between the energy storage battery pack and the compartment.

The compartment is semi-enclosed, with the battery packs entering and exiting through a single end face; both entry and exit are achieved via one end. The battery pack installation area is entirely inside the compartment, with the mechanical interface located on the bottom surface. The bottom interface of the battery pack is bolted to the interface structure inside the compartment. The overall space of the compartment is narrow, external operability is limited, and the assembly of the energy storage battery packs inside is challenging.

[0067] Implementation of Auxiliary Assembly Device

[0068] The auxiliary assembly device consists of a sliding module, a height lifting module, a load-bearing limiting module, and a base. These modules work together to assist in the assembly of the energy storage battery pack into the compartment. It is characterized by: a universal ball 1, a cylindrical pad 2, a platform 3, a lead screw 4, a worm gear reducer 5, a rocker wheel 6, a guide column 7, a swing bracket 8, a limiting hole 9, a limiting pin, a base structure 10, rollers 11, and feet 12.

[0073] (1) The sliding module mainly includes: universal ball 1, cylindrical pad 2, and platform 3; universal ball 1 is connected to cylindrical pad 2 by bolts, and cylindrical pad 2 is then connected to platform 3 by bolts. Universal ball 1 is orderly distributed on the plane of platform 3, reasonably avoiding the space for cable laying and the space for interference of cabin rods.

[0074] The above ordered distribution is as follows Figure 20 As shown, the omnidirectional balls are evenly distributed on both sides of the platform; in the middle area, in order to ensure load-bearing and sliding stability, an equilateral triangle configuration is adopted, that is, every 6 omnidirectional balls form an equilateral triangle, and the triangles are distributed in opposite directions in the central direction.

[0075] Platform 3 serves as the mounting plane for the array of omnidirectional balls 1 and cylindrical pads 2. It adopts a separate modular design, mainly based on the structural avoidance requirements of the compartment. Structurally, it has electrical cable avoidance area 301, compartment structure avoidance area 302, cylindrical pad mounting interface 303 and other mounting interfaces for connecting omnidirectional balls 1, cylindrical pads 2 and height lifting module.

[0076] (2) The height lifting module mainly includes: lead screw 4, worm gear reducer 5, rocker wheel 6, and guide column 7; the worm gear reducer 5 is connected to the platform 3 by bolts and cooperates with the lead screw 4.

The guide column 7 is bolted to the platform 3 and is distributed around the edge of the platform 3, mainly serving as a guide during the lifting process.

[0077] (3) The load-bearing limiting module mainly includes: a swing bracket 8, a limiting hole 9, and a limiting pin; the swing bracket 8 is fixedly connected to the base structure 10 by bolts, and the support position can be adjusted according to the axial direction of the compartment; the energy storage battery compartment is supported by the swing bracket 8, transferring the weight to the base structure 10; the limiting hole 9 cooperates with the limiting pin to realize the axial limiting of the compartment, specifically as follows: Figure 10 As shown, the mechanical interface hole of the compartment is aligned with the limiting hole [9], and the pin is inserted. The swing bracket 8 has a 90° rotation function in order to avoid obstacles during the placement of the compartment;

[0078] The swing bracket 8 consists of a swing bracket mounting structure 801, a swing bracket rotating structure 802, and a swing bracket contact structure 803. The swing bracket mounting structure 801 is connected to the base structure 10 by bolts. The swing bracket rotating structure 802 mainly realizes the 90° rotation function and completes the avoidance during the load-bearing process through clearance fit. The swing bracket contact structure 803 contacts the compartment and is equipped with polymer materials such as nitrile rubber to increase friction and buffer, which improves the limiting effect, increases the tolerance range, and avoids stress concentration caused by errors, thus preventing damage to the compartment structure.

[0079] (4) The base module mainly includes: base structure 10, rollers 11, and feet 12. The base structure 10 is the main structure and adopts a truss design to ensure stability; the rollers 11 are bolted to the bottom of the base structure 10 to facilitate the overall movement of the device; the feet 12 are bolted to the bottom of the base structure 10 to enhance the overall stability of the device during the assembly process.

In this example, the platform is separated into 3 small platforms. The height of each small platform is adjusted to be consistent.

[0087] g. When the energy storage battery pack reaches the vicinity of the mechanical interface area connecting with the compartment, the height is lowered by the height lifting module and it contacts the mechanical interface of the compartment. During the descent, the operator can achieve 2 degrees of freedom of movement and 1 degree of freedom of rotation adjustment in the plane to achieve the adaptation and adjustment of the mechanical interface. The operator adjusts the battery pack above the omnidirectional ball in the sliding plane. It can achieve movement in two directions, forward and backward and left and right, and can also rotate around the center of the plane.

[0088] h. Finally, the operators securely connect the energy storage battery pack to the compartment, and the installation process is complete;

[0092] The module with the installed energy storage battery pack is moved above the auxiliary assembly device. After the load-bearing area is determined, the swing bracket is rotated to the load-bearing state, and the module is lowered to complete contact. The limiting hole and the limiting pin of the connecting device are then connected. At this time, the relative positional relationship between the module and the device is determined.

[0093] The height adjustment module is operated to adjust the height of the sliding module platform to be relatively consistent, so that the array formed by the omnidirectional ball contacts the bottom of the energy storage battery pack;

[0094] The connecting parts between the compartment and the energy storage battery pack are disassembled. External force is used to make the energy storage battery pack slide stably out of the compartment, thus completing the disassembly.
